2 Select, revise or compile general technical regulations, engineering standards (or standard drawings) and procedure instructions for various types of equipment.
3 Prepare equipment purchase orders or technical specifications, draw inquiry version equipment schematics (equipment engineering drawings) and/or data sheets. At the same time, perform strength calculations and indicate wall thickness, size, weight, number of anchor bolts, etc. in the relevant inquiry documents. 4 Recommend the manufacturer for inquiry to the purchasing department and submit inquiry technical documents. 5 Provide equipment schematics (equipment engineering drawings) and/or data sheets and other relevant information to the relevant professionals. 6 Review the quotations of manufacturers, conduct technical analysis and evaluation, and fill in the technical evaluation form. Submit the procurement technical risk memorandum to the design manager when necessary.
7 Conduct technical contacts with the inquiring manufacturers, prepare and participate in the vendor coordination meeting (VCM), and be responsible for collating and signing the minutes of the meeting related to technical aspects. Participate in ordering work and handle technical issues related to ordering when necessary. 8 Revise the ordering technical documents, and modify the relevant equipment schematics (equipment engineering drawings) (ordering version), data sheets and other relevant technical documents according to the consensus reached in the vendor coordination meeting and before ordering. Provide the revised or updated technical documents to the relevant professionals. 9
Detailed engineering design
Review the preliminary confirmation (ACF) drawings and relevant technical information provided by the manufacturer for review. Perform local stress verification calculations based on the load data table of the connection point provided by the pipeline machinery (pipeline mechanics) specialty, and reinforce when necessary.
3Complete the equipment schematic diagram (equipment engineering drawing) and/or data sheet of the manufacturing version according to the ACF drawings provided by the manufacturer and the supplementary conditions provided by the relevant professionals. 4Provide the equipment schematic diagram (equipment engineering drawing) of the manufacturing version to the relevant professionals. Provide the layout, piping, building, and structure professionals with the preliminary confirmation (ACF) equipment outline drawing or general assembly drawing provided by the manufacturer for review. Review the final confirmation (CF) drawings and relevant technical information provided by the manufacturer. 5
